So here's a little factoid for you: Today, February 13, Duke coach Mike Krzyzewski turns 60 years old. It's strange to think of him as that old; not only does he continue to be that irrepressible lovable impish scamp that we all adore, but he also has retained his thick, lustrous black hair. (Because Coach K would never lower himself to dyeing it, never.)

As Coach K enters his seventh decade of life, with his team struggling as it hasn't struggled in a decade, we ask ourselves: How does Coach K do it? How does he remain so full of life and good cheer? How is he able to continue to bring hope and vigor to millions of sports fans every year?
